A scientist is examining an unknown solid. Which procedure would most likely help determine a chemical property of the substance?

A chemical property describes how a substance can change into a different substance. Exposing the solid to a flame tests whether it reacts by burning, so the correct choice is B, exposing it to a flame to see if it catches on fire. Melting point, brittleness or flexibility, and solubility are physical properties because they can be observed without changing the substance’s chemical identity.
